Most people unfortunately limit the meaning of sobriety to the absence of alcohol, but scripturally speaking, the meaning involves a much broader scope. Sobriety is the opposite of being beside oneself (2 Corinthians 5:13) or mad (Acts 26:25) and is akin to being alert (1 Thessalonians 5:6). The word sober is used in conjunction with the words grave (1 Timothy 3:11; Titus 2:2) and temperate (Titus 1:8; Titus 2:2) indicating that it is accomplished when one is in control, down to earth, and finds the proper balance in his thoughts and actions. One who is sober is humble (Romans 12:3), not drunken (1 Thessalonians 5:7-8), and well aware of the circumstances surrounding him at all times (1 Thessalonians 5:6, 8; 1 Peter 5:8).
The Bible seems to point to Pharaoh most often as an example of someone with a heart hardened through sin and the deceitfulness of power and fame. Pharaoh's hardened heart led him from one rebellious act to the next. He constantly fought against the Lord and the Lord’s man. Even after all of the miracles in Egypt and the abundance of judgments, he chose to pursue the children of Israel as they departed from Egypt. Pharaoh's hardened heart led him to pursue them to the Red Sea. Out of all the troublesome effects of a hard heart, the most troubling aspect is that it refuses to hearken to the words of the Lord. On at least five occasions, the Lord makes this connection (Exodus 7:13, 22; Exodus 8:15, 19; Exodus 9:12). A hard heart closes the ears to the truth and sets the individual up for greater judgment.
